Patent JP-H03120412-A (JP)
Title: Displacement measuring instrument
Inventor: HORII TAKAYOSHI
IPC: G01C3/06
Filed: 1989-10-02
Abstract: PURPOSE:To obtain an output in linear relation corresponding to the variation in the distance from a reference position to a body to be measured by constitut ing an arithmetic means including a voltage dividing means which performs voltage division between the voltage signals of the 1st and 2nd converting means at a predetermined ratio and a dividing circuit means. CONSTITUTION:A position detecting element 18 outputs two photocurrents IA and In corresponding to the position of a light spot. The photocurrents IA and In are converted by current-voltage converting circuits 22 and 24 into voltage signals VA and VB. A variable resistor RV is interposed between the output terminals A and B of the converting circuits 22 and 24. A voltage VC which is divided to K:(1-K) viewed from the opposite side of an output terminal B from a projection optical axis is led out of the movable terminal C of the resistor RV. The voltage VC is represented as VC=VB+K(VA-VB). When the movable terminal C is adjusted so that K satisfies a specific expression, a linearization correcting circuit 20a consisting of the variable resistor RV obtains the output (v) of the divider 30 in the linear relation with the displacement (x).
